bacco pipe.

More particularly the invention relates to a pipe designed to providebetter and surer draft than is ordinarily had in tobacco pipes; also toprevent passage of moisture from the mouth piece to the bowl, andpassage of tobacco particles, juice and nicotin to the mouth;furthermore, to prevent clogging of the stem and bowl; and to permit ofready cleaning of all parts. I am aware that pipes have been constructedwhich are alleged to have some or all of these advantages. Such pipeshave, however, usually been of complicated, or expensive structure, andof an unnecessary number of parts; often resulting in an article ofgrotesquev on inartistic design, and sometimes involving metal bowls,double chambers and other useless or ob ect1onable features.

The object of the present invention is a pipe of the charactermentioned, in which the number of parts is reduced to a minimum; alsoone in which the pipe body and bowl may be integral, and of wood, orother accepted pipe material, having the flavor and coloring qualitiesdemanded by critical pipe smokers and which in its entirety may be ofpleasing and accepted deslgn.

The above and other features of the invention will more fully appearupon reference to the accompanying drawmgs in which- Figure 1 is a Viewin elevation the assembled pipe. Fig. 2 is a view in cross sectionalelevation of the pipe bowl. Fig. 3

is a perspective view of the cap which closes the bottom of the bowl.Fig. 4 is a perspective view of the pipe bowl.

Referring to the drawings, the pipe bowl 1 is shown of one piece withthe stem 2;

which latter has attached thereto, in any suitable manner, a mouth piece3. The parts 1 and 2, which form the body of the pipe, are preferably ofwood, meerschaum, or

other popular pipe material, such as will If desired,

however, the parts 1 and 2 may be separable, and may be of any suitablematerial. It will be noted that the exterior designs of the bowl andstem 2 shows nothing unusual in pipe construction.

Referring now to Fig. 2, it will be seen that the smoke passage 4. ofthe stem does not connect in the usual manner with the tobacco chamber 5of the bowl. From the chamber 5there is a passage (5 which terminates atan opening 7 in the bottom of the bowl. The stem smoke-passage 4 leadsdirect to the bottom of the bowl, and terminates at the opening 8therein. The bowl, for a short distance above the bottom thereof, is ofcylindrical shape; and the cylindrical portion is exteriorly threaded,as shown at 9, to receive a cap. The cap (see Fig. 3) is in the form ofa cylindrical cup, the base 10 of which is closed, and the top of whichis open. The cup is threaded interiorly at 11 for engagement with thethread 9 on the bowl. Concentric with the base of the cup, and solderedor otherwise rigidly secured thereto, is a tubular member 12, havingopenings 13 through the side thereof at some distance above the base 10.The length of the tubular member 12 is such that when the cap is screwedhome on the bowl, the upper edge of the tube will lie within a circularcut 14 in the bottom of the bowl, whereby the top of the cup is closedand sealed against passage of smoke. The cap may be provided with amilled edge 15 to provide a grip for the fingers in removing andaflixing the cap. The cap and the tubular member 12 may, in whole or inpart, be of metal, rubberoid, wood or of any suitable material.

In operation, the tobacco is held in the bowl 5.- The passage 6, fromthe bowl cham her 5, is small enough to prevent escape of tobacco,except of dust and the like; but permits of free passage of smoke.Liquid or solid matter from the bowl will for the most part be caught inthe bottom of the tube 12. The smoke, however, passes from the interiorof tube 12, by way of openings 13, into the annular space 16 between thetube and the outer wall of the cap. The opening 8 from the smoke passageof the stem registers with the annular chamber 16, so that the smokepassing from the interior of the tube 12, by way of openings 13, maythen enter the stem passage 4:, at which time it is cleared of liquidsand solids, the latter having been deposited in the tube 12, or in thechamber 16. saliva which may pass down the stem will be deposited in theannular chamber 16 and cannot get to the bowl. Saliva in the chamber 16will catch and hold any tobacco dust or other matter which is fineenough to pass the opening 13 with the smoke. The bowl is consequentlykept dry and does not clog; and as nothing but smoke and saliva get intothe stem, this also will not clog. When the accumulations in the tube,or in the annular "chamber outside 01" the tube, warrant it, the cap maybe unscrewed and cleaned out; whereupon the pipe, on replacement of thecap, is again substantially as clean as when originally used.

It will be noted that the only necessarily adjustable or removable partis the cap. Also that the stem passage has no abrupt turn; wherefore, astraw or the like. can be readily passed from one end to the other ofthe stem to remove any obstacle which may accidentally enter from eitherend. The passage from the top of the bowl tothe bottom thereof is alsowithout turns; and, in event any tobacco or other obstacle should I bychance clog the passage 6, it may easily be removed. 7

A preferred form of the invention has been shown in the drawings. Itwill readily be understood, however, that, within the scope of theinvention, the shape, material, number of parts, and other features 01the pipe, may be considerably modified or changed.

VJ hat I claim is: I

1. A tobacco pipe having a tobacco receptacle; a cup below thereceptacle in sealed engagement therewith means whereby the cup may bedetachably secured as a whole directly to the receptacle, said cupcomprising two chambers, each closed at the bottom, but in connectionwith each other above the bottom; a stem, the smoke passage of whichopens into one of said chambers, and said receptacle having a passagefrom of the receptacle being in communication with the other of saidchambers.

3. 21 tobacco pipe havinga tobacco re- A ceptacle; a cup, the open endof which is threaded onto the base of the receptacle; a hollow memberclosed at the bottom, integral with the cup, of less diameter than thecup, and concentrically seated within the cup, the interior or whichhollow member is in communication with the interior of the receptacle,and also with the chamber between the cup and said hollow member, and astem in communication with said last named chamber.

a. A tobacco pipe having a tobacco receptacle; a cup, the open end ofwhich is detachably secured to the base of the receptacle; a hollowmember closed at the bottom, integral with the cup, of less diameterthan the cup, the interior of which hollow member is in communicationwith the interior of the receptacle, said cup being closed at'its top bythe bottom of the receptacle except for said communication with theinterior of the receptacle, but having an opening through its side intothe chamber between it and the wall of the cup, and a stem incommunication with said last named chamber.
